As international solidarity and cooperation become ever more crucial in the age of COVID-19, efforts in the international community to respond to global issues in the post-COVID-19 era are also receiving a major boost- In particular, the United States, EU and other leading nations held a virtual climate summit in April 2021, announced their 2030 greenhouse gas re-duction goals and are actively promoting decarbonization policies and sus-tainable growth- In response to the global pandemic crisis, discussions on green ODA to support climate change action and green transition in developing countries are also in full swing- At the P4G Seoul Summit held in May last year, the Korean government pushed for transition to a low-carbon economy through Green New Deal policies and “net zero by 2050” strategies, together with plans to expand support for developing countries seeking green recovery by 2025- In addition, the Committee for International Development Cooperation (CIDC) convened in July last year to establish the Green New Deal ODA Promotion Strategy, which aims to achieve the goal of ex-panding green ODA- Development cooperation in the green sector currently accounts for 20% of the total ODA (2015–2019 average), but the Korean government plans to significantly in-crease the proportion of ODA in the green sector to above the OECD average (28-1%) by 2025- In order to lead global cooperation in the green sector to sustain momentum for green transition and boost efforts in the international community, the Korean government has pledged $300 mil-lion in support for the Green Climate Fund (GCF) by 2027- It also plans to expand cooperation with the Global Green Growth Institute (GGGI) through the establishment of a Green New Deal Fund to support consulting and financing green industry activities for developing countries in five major Green New Deal areas- In order to enhance the effectiveness of ODA in green sectors and strengthen development partnerships, it is necessary to focus on areas such as green energy and eco-friendly mobility in developing countries and promote capacity development-
